In 1935, avid sailor Paul Sperry took a cue from the grooved paws of his surefooted dog and designed the first nonslip sole for boat shoes. Immensely popular from the beginning, the Sperry Top-Sider became the official shoe of the U.S. Navy in WWII and the America's Cup in the 1980s. Today, Sperry outfits men, women and kids with shoes and clothing for a seaworthy lifestyle.
